Ice is watter frozen intae a solid state. It can appear transparent or opaque bluish-white colour, dependin on the presence o impurities or air inclusions. The addeetion o ither materials such as soil mey further alter its appearance.
Ice appears naiturally in furms o snawflauchts, hail, icicles, ice spikes an candles, glaciers, pack ice, frost, an polar ice caps. It is an important component o the global climate an plays an important role in the watter cycle. Furthermair, ice haes numerous cultural applications, frae ice cuiling o drinks tae winter sports tae the airt o ice sculptin.
The molecules in solit ice mey be arranged in numerous different ways, cried phases, dependin on the temperatur an pressur. Typically, ice is the phase kent as ice Ih, which is the maist abundant o the varyin solid phases on Yird's surface. The maist common phase transeetion tae ice Ih occurs when liquid watter is cuiled belaw 0°C (273.15K, 32°F) at staundart atmospheric pressur. It can an aa deposit frae vapour wi na intervenin liquid phase, such as in the furmation o frost.
